Today I am doing a basic u-joint change on a Yamaha Grizzly 450. The owner changed a front wheel bearing himself, but did not want to change the u-joints on the rear drive shaft. This machine has 9600 miles on it and the wheel bearing and u-joints are the only problems that the machine has had.
The drive shaft is very hard to get to, even after removing the skid plate from the bottom of the machine it is difficult to access. Other than that it was a typical u-joint job, press or drive the cups out of the yokes, clean the yokes up (a round wire brush in a drill works great), then press the new cups in. After finishing the drive shaft I fixed a leak on a front brake line (from the owners bearing replacement).
Total time on this job: 4 hours.
